［摘要］在预制混凝土夹心保温外挂墙板与主体结构间设置U型钢板消能器形成的减震外挂墙板，在地震作用下可利用外挂墙板与主体结构间的相对滑移变形耗散地震能量，从而达到减小主体结构损伤的目的。在对含减震外挂墙板装配式混凝土联肢剪力墙进行拟静力试验研究的基础上，对其数值模拟分析方法进行了研究。提出了两种分别适用于构件层次和结构层次的精细和简化有限元模型的建模方法。采用两种模型对试验试件的受力性能进行了数值模拟分析，并与试验结果进行了对比。结果表明，两种模型均有较高的计算精度，能够较好地反映结构的受力情况。

Abstract:The energy dissipating cladding panel formed by a U-shaped steel damper is set between the precast concrete sandwich cladding panel and the main structure. Under the action of an earthquake, the relative sliding deformation between the cladding panel and the main structure can be used to dissipate seismic energy to achieve the purpose of reducing the damage of the main structure. On the basis of the pseudo-static test research on the prefabricated concrete joint shear wall with energy dissipating cladding panel, the numerical simulation analysis method was studied. Two modeling methods of fine and simplified finite element models, which are suitable for component level and structure level, were proposed. Two models were used to carry out numerical simulation analysis on the mechanical properties of the test specimens, and the results were compared with the test results. The results show that the two models have higher calculation accuracy and can better reflect the force of the structure.
